Have a Rem R1 on its way to me via a raffle and want to start doing some bullseye shooting with it. I am hearing that the "Enhanced" model has a dovetail size that will fit Bo-Mar sights, but I cannot seem to get a solid answer as to what sights will fit the dovetail on the std R1 model. According to customer service at Remington, it is a metric size.

Anyone here have the actual dimensions so that I can start looking at various sights? The front dovetail as well if you know it would be helpful.
